In a letter published Wednesday, the senators cite a specific tweet from the Judiciary Committee’s Twitter account, which is run by the Republicans' staff.

That tweet claims previous background checks failed to turn up any evidence of alcohol abuse or sexual misconduct. But Democrats say they reviewed the same background checks and that they feel the tweet is inaccurate.

The Judiciary Committee account responded to the letter Wednesday evening, writing "nothing in the tweet is misleading" and calling the Democrats' letter a "false smear."
